Macos High Sierra Unsupported Mac

For the first time since Apple released OS X 10.8 Mountain Lion in July 2012, Apple has dropped support for a number of older Macs that had supported OS X 10.8 through 10.11 El Capitan. No MacBook and iMac models prior to Late 2009 and no MacBook Air, MacBook Pro, Mac mini, and Mac Pro models prior. OS X El Capitan (10.11) on Unsupported Macs macOS Extractor and MacPostFactor are apps that guide you through patching and installing OS X El Capitan (10.11), Yosemite (10.10), Mavericks (10.9), or Mountain Lion (10.8) on your older Mac. Whilst it does lessen security somewhat, it is not the end of the world, and OS versions prior to El Capitan do not include it anyway.

Question: I read somewhere that it is possible to install the latest version of OSX 10.10 Yosemite on my Mac, even though the official installer refuses to install. Can you give me any directions? Answer: Installing newer versions of OSX on slightly older Macs that do not meet the official system requirements. I am currently researching installing OS X 10.13 High Sierra on unsupported Macs. I did the Sierra upgrade on a couple of MacPros 4,1 and it has worked excellently, after I did a firmware update patch to get it to read as a MacPro 5,1, so I am very optimistic on doing it again.

For the first time since Apple released OS X 10.8 Mountain Lion in July 2012, Apple has dropped support for a number of older Macs that had supported OS X 10.8 through 10.11 El Capitan. No MacBook and iMac models prior to Late 2009 and no MacBook Air, MacBook Pro, Mac mini, and Mac Pro models prior to 2010 are officially supported by macOS Sierra, although workarounds have been developed for most unsupported 2008 and 2009 Macs.

Mac OS X is no longer being called OS X, and Apple is not promoting Sierra with a version number either (however, it is internally identified as OS X 10.12). Now it’s simply macOS Sierra – in keeping with iOS, tvOS, and watchOS.

I did the Sierra upgrade on a couple of MacPros 4,1 and it has worked excellently, after I did a firmware update patch to get it to read as a MacPro 5,1, so I am very optimistic on doing it again. At the time I did it last year, it appeared that it couldn't be done on the 2008 MacPro. MacOS High Sierra on Unsupported Macs. For the first time since OS X Mountain Lion (10.8) in 2012, macOS Sierra (10.12) changed the official minimum requirements needed for installation, leaving.

macOS Sierra was released on Sept. 20, 2016 and officially requires a supported Mac with at least 2 GB of system memory and 8.8 GB of available storage space. (We recommend at least 4 GB of RAM.)

Officially Supported Macs

All Late 2009 and later MacBook and iMac models are supported in macOS Sierra, as are all 2010 and newer MacBook Air, MacBook Pro, Mac mini, and Mac Pro computers.

Hacking macOS Sierra for Unsupported Macs

Hardware requirements for macOS Sierre include a CPU with SSE4.1, so it cannot be run on any Mac with a CPU prior to the Penryn Core 2 Duo. In theory, it should be possible to get Sierra running on any Penryn or later Mac. It may be possible to swap out the Merom CPU in some Macs for a Penryn, which would then allow Sierra to run.

Sierra can run with 4 GB of system memory, but as with all recent versions of OS X, more memory will allow it to run even better.

Colin Mistr has published a macOS Sierra Patch Tool, which currently allows you to install and run macOS Sierra on the following officially unsupported hardware:

  • Early 2008 iMac or later
  • Mid 2009 MacBook (white) or later
  • Late 2008 MacBook Air or later
  • Early 2008 MacBook Pro or later
  • Late 2009 Mac mini or later
  • Early 2008 Mac Pro or later

Note: If you have the Early 2009 Mac Pro and have installed the firmware update patch so it identifies itself as MacPro5,1, you can run the standard installer. You do not need the patch tool.

You will need a USB drive 8 GB or larger and Mistr’s patch tool, which is linked on his page. WiFi does not function on these unsupported systems if they have the Broadcom BCM4321 WiFi module:

New Features

Siri comes to the Mac with macOS Sierra.

macOS Sierra can automatically sync all files on your Desktop and in your Documents folder with other Macs running Sierra. You can also access these files in your iPhone or iPad using iCloud Drive.

The new Universal Clipboard lets you copy on one device and paste on another – whether it’s a Mac with Sierra or an iPhone or iPad with iOS 10.

Tabs are almost everywhere in Sierra, and they work much as they do in your browser. Third party apps will also be able to use tabs.

Apple Pay is now part of macOS, not just iOS.

If you have an Apple Watch, Auto Unlock will authenticate you and log you in automatically when you approach your Mac.

Apple's OS X El Capitan in October got off to the fastest-ever one-month start for a Mac operating system.

El Capitan, also tagged by Apple as OS X 10.11, was released on the last day of September: 31 days later it had been installed on another 25% of all Macs, bumping its total to 27%, according to U.S. analytics firm Net Applications.

The October increase was the largest one-month user share gain by an edition of OS X in the six years that Computerworld has recorded Net Applications' data, beating Mavericks and Yosemite, the two previous upgrades Apple handed out free of charge.

Net Applications estimates operating system shares by tallying unique visitors to its clients' websites. In the absence of definitive data from Apple, user share is one of the few proxies for real-world OS X adoption.

When the release dates of each edition were taken into account, however, El Capitan's average daily adoption rate only edged Yosemite's and turned out to be lower than Mavericks'. Those forerunners launched in the second half of October in 2014 and 2013, respectively, and so spread their biggest gains over a longer stretch than El Capitan: 41 days for Mavericks and 47 days for Yosemite.

Not surprisingly, the majority of those who migrated to El Capitan came from its immediate predecessor, Yosemite. Last month, Yosemite shed more than a third of its user share as its users upgraded.

But other, even older versions of OS X also lost user share last month. Each of those tracked by Computerworld -- from 2007's Leopard on -- fell at rates larger than their average decline over the previous 12 months. Mavericks, for instance, fell to 14% of all editions of OS X, a two-point slide that was double its earlier average.

High

Approximately 90% of all Macs were eligible to upgrade to El Capitan when the operating system launched on Sept. 30. El Capitan will run on the same Macs that have run Yosemite, Mavericks, 2012's Mountain Lion and 2011's Lion.

On the flip side, a sizable number of Macs continued to run outdated editions of OS X last month. By Net Applications' data, about 16%, representing one in six Macs, was powered by a version that Apple no longer supports with security updates. Apple distributed the final security update for the three-year-old Mountain Lion in August. It continues to patch Mavericks and Yosemite, however.

The one-in-six who run unsupported operating systems seems to be the natural order. Not only has that same percentage of OS X users been on the retired list in earlier years -- even as new editions rolled out annually -- but in the Windows world, a double-digit fraction still run Windows XP, which left support more than a year and a half ago.

The free El Capitan upgrade can be obtained from Apple's Mac App Store, and supports iMacs as old as mid-2007, MacBook Pro notebooks from late 2007 on, and MacBook Air laptops from late 2008 going forward.

Apple previously released security updates to defend against Spectre—a series of speculative execution vulnerabilities affecting devices with ARM-based and Intel CPUs. Intel has disclosed additional Spectre vulnerabilities, called Microarchitectural Data Sampling (MDS), that apply to desktop and notebook computers with Intel CPUs, including all modern Mac computers.

macOS Mojave 10.14.5 includes security updates for Safari, and the option to enable full mitigation, as described below.

Security Update 2019-003 High Sierra and Security Update 2019-003 Sierra include the option to enable full mitigation.

About security fixes in macOS Mojave

macOS Mojave 10.14.5 fixes this issue for Safari with no measurable performance impact.1 This update prevents exploitation of these vulnerabilities via JavaScript or as a result of navigating to a malicious website in Safari.

Customers can also protect their Mac by updating security settings in macOS to download apps only from the App Store. This setting helps prevent the installation of apps that could potentially exploit these vulnerabilities. All apps from the App Store are signed by Apple to ensure that they haven’t been tampered with or altered. Learn how to view and change app security settings on your Mac.

Although there are no known exploits affecting customers at the time of this writing, customers with computers at heightened risk or who run untrusted software on their Mac can optionally enable full mitigation to prevent harmful apps from exploiting these vulnerabilities. Full mitigation requires using the Terminal app to enable an additional CPU instruction and disable hyper-threading processing technology. This capability is available for macOS Mojave, High Sierra, and Sierra in the latest security updates and may reduce performance by up to 40 percent2, with the most impact on intensive computing tasks that are highly multithreaded. Learn how to enable full mitigation.
